[4] One measure of alternative fuels in the U.S. is the "gasoline-equivalent gallon" (GEG). In 2002, the U.S. used as motor fuel, ethanol equal to 137,000 terajoules (3.8 × 10 10 kWh), the energy equivalent of 1.13 billion US gallons (4.3 gigalitres) of gasoline. This was less than 1% of the total fuel used that year.
Assuming initial atmospheric conditions (1 bar and 20 °C), the following table [1] lists the flame temperature for various fuels under constant pressure conditions. The temperatures mentioned here are for a stoichiometric fuel-oxidizer mixture (i.e. equivalence ratio φ = 1).

A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
Instead the formula that would fit some of the Bonales data is k ≈ 2.0526 - 0.0176TC and not k = -0.0176 + 2.0526T as they say on page S615 and also the values they posted for Alexiades and Solomon do not fit the other formula that they posted on table 1 on page S611 and the formula that would fit over there is k = 2.18 - 0.01365TC and not k ...
